ObjectiveTo investigate the changes in chemical components of Gardeniae Fructus(GF) before and after being charred, providing data support for research on the material basis of GF Carbonisata(GFC). MethodsUltra-performance liquid chromatography-quadrupole-electrostatic field orbitrap high-resolution mass spectrometry(UPLC-Q-Orbitrap MS/MS) was used to conduct a comprehensive analysis of the chemical components in GF and GFC under positive and negative ion modes with Compound Discoverer 3.3 software and online database. Then, principal component analysis and partial least squares-discriminant analysis in SIMCA14.1 software were used to analyze the MS data of each sample. Based on the principle of variable importance in the projection(VIP) value>1, differential secondary and primary metabolites before and after carbonization were screened. In addition, MetaboAnalyst website was used for pathway enrichment of Kyoto Encyclopedia of Genes and Genomes(KEGG), so as to provide a reference for clarifying the processing mechanism. ResultsA total of 185 components were identified, including 96 secondary metabolites and 89 primary metabolites. These components were classified into nine categories, primarily including iridoid glycosides, flavonoids, and terpenoids, their fragmentation pathways were also analyzed. Simultaneously, multivariate statistical analysis was performed on the secondary and primary metabolites, identifying 70 and 59 differential metabolites, respectively. The secondary metabolites were enriched in two metabolic pathways, including C5-branched dibasic acid metabolism and flavonoid and flavonol biosynthesis, while the primary differential metabolites were enriched in seven pathways such as linoleic acid metabolism and tyrosine metabolism. ConclusionThe chemical components of GF change significantly after carbonization, with a significant decrease in the contents of iridoid glycosides and terpenoids such as hydroxyisogeniposide, crocin Ⅱ, crocetin, and jasminoside B. while the contents of 4-hydroxycoumarin, geniposidic acid, gentiopicroside, and gardenoside methyl ester increase significantly. This change is presumed to be associated with the enhanced cooling and hemostatic effects of the processed products. The identified key components provide a basis for elucidating the material basis underlying the efficacy changes before and after carbonization.

Objective To evaluate the effectiveness of schistosomiasis surveillance in Jiangsu Province during the stage moving from transmission control to transmission interruption, and to analyze the current risk and challenges, so as to provide the evidence for achieving the target of schistosomiasis elimination. Methods Schistosomiasis surveillance data were collected from Jiangsu Province from 2012 to 2024, and the endemic areas, Schistosoma japonicum infections in humans and livestock, Oncomelania hupensis snail distribution and implementation of integrated interventions were descriptively analyzed. In addition, the trends in areas with snails, seroprevalence of human S. japonicum infections and numbers of advanced schistosomiasis cases were assessed using a Joinpoint regression model. Results The endemic areas of schistosomiasis continued to shrink in Jiangsu Province from 2012 to 2024, with the number of schistosomiasis-eliminated counties (cities, districts) increasing from 53 (75.71%) to 63 (96.92%), and interruption of schistosomiasis transmission was achieved across the province. A total of 4 600 300 person-times were tested for serum antibodies against S. japonicum, with 28 719 person-times positive detected; and 616 500 person-times were tested S. japonicum infections among local residents in Jiangsu Province from 2012 to 2024, with only 3 egg-positives detected, and no egg-positives found since 2017. A total of 187 600 herd-times were tested for schistosomiasis in livestock, and no S. japonicum infections were found. O. hupensis snail survey was performed covering 1 018 408.97 hm2, and a total of 35 556.35 hm2 was found with snail-infested habitats, including 174.40 hm2 of emerging snail-infested habitats. A total of 1 102 800 O. hupensis snails were identified for S. japonicum infections, and no infections were found. The areas of snail-infested habitats appeared a tendency towards a rise in Jiangsu Province from 2019 to 2023 (APC = 23.67%, P < 0.05), and the actual areas of snail-infested habitats appeared a tendency towards a decline from 2012 to 2015 (APC = −22.77%, P < 0.05), and towards a rise from 2015 to 2023 (APC = 9.76%, P < 0.01). The seroprevalence of anti-S. japonicum antibodies appeared a tendency towards a decline among residents in Jiangsu Province from 2017 to 2023 (APC = −14.92%, P < 0.01). In addition, the number of newly diagnosed advanced schistosomiasis cases appeared a tendency towards a decline from 2012 to 2024 (APC = −12.02%, P < 0.01), and the numbers of advanced schistosomiasis patients requiring treatment showed a tendency towards a decline from 2012 to 2021 (APC = −10.56%, P < 0.01) and from 2021 to 2023 (APC = −20.06%, P < 0.01). Conclusions Great progresses had been achieved in schistosomiasis control in Jiangsu Province following transmission control, and transmission interruption had been achieved; however, there are still snail-infested habitats. High-intensity surveillance and integrated control are required to be maintained to advance the achievement of the target of schistosomiasis elimination in Jiangsu Province.

Objective To investigate the epidemiological characteristics and changing trend of typhus in Shaanxi Province from 2005 to 2023 to provide a scientific basis for its prevention and control. Methods Excel 2007, SPSS 25.0, Joinpoint 4.9.1.0, and Geoda 1.6 were used for data collection and statistical analysis. Super Map was used for data visualization to describe the changing characteristics of the disease. Results A total of 394 typhus cases were reported in Shaanxi Province from 2005 to 2023. The average annual incidence of typhus was 0.054/100 000, showing a dynamic fluctuation trend(AAPC=-3.3, t=-0.3, P>0.05). The cases were mainly concentrated in Baoji, Hanzhong and Xi′an, accounting for 78.68%. The incidence peak was from May to October, accounting for 64.21% of annual incidence. The epidemic season was from May to October and December. The incidence of the disease was concentrated in the 40-69 age group, accounting for 58.88%, and the sex was 1.07:1. The main occupation was farmers, accounting for 72.08%. The median time from onset to diagnosis was 7 days. Global spatial autocorrelation analysis showed that there were significant spatial autocorrelations in 11 years from 2005 to 2023(P<0.05). Local spatial autocorrelation analysis detected a total of 43“high-high”clustering areas, mainly concentrated in Baoji City. Conclusions The overall incidence of typhus in Shaanxi Province showed a dynamic fluctuation trend, with notable seasonal and regional aggregation. The incidence of typhus was higher in middle-aged and elderly people in rural areas. Surveillance should be strengthened in typhus endemic areas in summer and autumn, and health education should be conducted for key population to form good health habits and reduce the incidence of typhus.

Objective To explore the efficacy and safety of blue laser vaporization in the treatment of large-volume (>80 mL) benign prostatic hyperplasia (BPH). Methods A retrospective analysis was conducted on the clinical data of 149 BPH patients with prostate volume>80 mL who underwent blue laser vaporization at our hospital during Aug. 2023 and Aug. 2025. The 1-month postoperative maximum urinary flow rate (Qmax) and international prostate symptom score (IPSS), operation time, postoperative hemoglobin drop, bladder irrigation volume, catheter indwelling time, and incidence of postoperative complications were recorded and analyzed. Results All operations were successfully completed, without conversion to other approaches. The operation time was (41.47±11.05) minutes, postoperative hemoglobin drop (2.78±1.19) g/L, bladder irrigation volume (9.97±1.49) bags, and catheter indwelling time (3.30±1.85) days. One month after surgery, the Qmax was significantly higher than the preoperative value [(20.19±3.39) mL/s vs. (2.39±2.17) mL/s], while the IPSS was significantly lower [(4.46±0.87) vs. (27.69±2.06)], with statistically significant differences (P<0.001). Postoperative complications included 1 case of incontinence (0.67%), 2 cases of urethral stricture/bladder neck contracture (1.34%), and 1 case of secondary bleeding (0.67%), all of which improved with symptomatic treatment. Conclusion Blue laser vaporization is effective for treating large-volume BPH, with advantages such as minimal bleeding risk, short operation time, fast recovery and safety.

Objective To construct a dynamic prediction model for JC polyomavirus (JCV) reactivation after kidney transplantation. Methods A retrospective analysis was conducted on the clinical data of 128 recipients who met the inclusion criteria and received kidney transplantation in Nanfang Hospital, Southern Medical University, from June 2021 to December 2024. Dynamic Cox regression and dynamic restricted mean survival time (RMST) regression based on the landmark method were adopted to establish the dynamic prediction models, and Monte Carlo cross-validation was used to evaluate model performance. Results The dynamic models could predict the incidence and onset time of JCV reactivation within the subsequent 3 months according to covariates at each landmark time point from the 1st to the 6th month after transplantation. Remuzzi score, body mass index and warm ischemia time were independent risk factors for JCV reactivation, while a history of urinary BK polyomavirus reactivation served as a protective factor. The median values of the area under the curve, C-index and Brier score of the dynamic Cox model were 0.873, 0.851 and 0.065 respectively, and the C-index of the dynamic RMST model was 0.829, all of which were superior to those of the static model. Conclusions The landmark-based dynamic models exhibit excellent predictive performance, which may integrate baseline data and post-transplant follow-up information to realize dynamic assessment of the risk and time window of JCV reactivation, thereby providing evidence for optimizing post-operative monitoring and individualized intervention strategies.

Objective On the basis of the theory of the tumor metastatic state, this work aims to explore the metastasis trajectories and peripheral immune response patterns in patients with non-small cell lung cancer (NSCLC) receiving vital qi-strengthening and toxin-eliminating therapy (Fuzheng Juandu) and reveal the value of peripheral immunity in assessing vital qi deficiency during metastasis. Methods A retrospective study design was adopted. Patients with NSCLC admitted from January 1, 2018, to October 31, 2025 were enrolled. Data on metastasis status and peripheral immune indices were collected at the follow-up time points of one, two, three, and five years. Group-based trajectory modeling was used to fit metastasis trajectories, and the independent predictors of trajectory grouping were analyzed through multifactor and multiclassification logistic regression. Results A total of 184 patients with NSCLC were included, and three different groups of metastasis trajectories were identified, namely, the low-risk stable (46.74%, n=86), low-risk rising (13.59%, n=25), and high-risk stable (39.67%, n=73) groups. Univariate analysis revealed substantial differences in peripheral immune indices among the three trajectory groups. Multivariate analysis showed that TNM stage, absolute neutrophil count, lymphocyte count, absolute monocyte count, platelet volume, SAA:CRP ratio, and NLR were independent predictors of the low-risk rising group, whereas TNM stage, absolute monocyte count, basophil count, SII, and NLR were independent predictors of the high-risk stable group. Conclusion Under Fuzheng Juandu therapy, patients with NSCLC exhibit three distinct metastasis trajectories, each

ObjectiveTo analyze the volatile components in raw Coptidis Rhizoma, Euodiae Fructus juice-processed Coptidis Rhizoma (Yuhuanglian), and the processing adjuvant Euodiae Fructus juice, identify marker volatile components in the processed product, and elucidate the material basis changes during the processing with Euodiae Fructus juice. MethodsHeadspace solid-phase microextraction coupled with gas chromatography-quadrupole-time-of-flight mass spectrometry (HS-SPME-GC-Q-TOF-MS) was employed to analyze the volatile components in raw Coptidis Rhizoma, Yuhuanglian, and Euodiae Fructus juice. Chemometric analysis was performed to compare volatile components among samples and screen the marker components. Finally, the relative odor activity value (ROAV) was calculated to investigate odor characteristics. ResultsA total of 127 components were detected, with 27, 75, 84 volatile components identified in Euodiae Fructus juice, raw Coptidis Rhizoma, and Yuhuanglian, respectively. Processing with Euodiae Fructus juice significantly increased the number and content of volatile components. Chemometric analysis revealed significant changes in volatile components among the three sample types, allowing clear discrimination. After processing, 39 components such as methyl octanoate and allyl propionate were introduced, while 34 components including furfural and hexanoic acid increased in content, and 11 components including butyric acid and octanal decreased. Additionally, eight components, including zingiberene, 6-methyl-6-hepten-2-one, and 5-methyl-2-hexanone, were screened as marker components of Yuhuanglian. Moreover, processing enhanced the ROAV values of 2,5-dimethylpyrazine (roasted, nutty, coffee-like aroma), 3-ethylphenol, and guaiacol (smoky, woody aroma). Additionally, it incorporated 1-hepten-3-one from Euodiae Fructus juice and the newly generated 1-hexen-3-one, contributing mushroom and cucumber-like odors. The sensory profile of Yuhuanglian integrated nutty, roasted, smoky, and woody notes with the citrus and fruity aroma originally contributed by octanal. ConclusionThe processing with Euodiae Fructus juice introduced components from adjuvant, significantly altering the volatile component profile and enhancing the sensory odor characteristics of Yuhuanglian. This study provides a valuable reference for exploring the material basis of volatile components and establishing processing specifications for Yuhuanglian.

To evaluate the clinical value of nebulized indocyanine green(ICG) combined with near-infrared fluorescence imaging for intraoperative detection of air leaks during pulmonary resection. This was a two-center randomized controlled trial enrolling patients undergoing thoracoscopic pulmonary resection. After enrollment, patients were randomly divided into an experimental group and a control group. The experimental group received nebulized ICG and fluorescence imaging in addition to the conventional water immersion test, while the control group underwent the water immersion test alone. Intraoperative air leak detection and postoperative air leak incidence were compared between the two groups. Multivariable logistic regression analysis was performed to assess the association between ICG nebulization intervention and postoperative air leaks after adjusting for confounding factors including age, sex, smoking history, history of respiratory disease, surgical procedure, and study center. A total of 181 patients were enrolled(90 in the experimental group, 91 in the control group). The experimental group showed significantly higher intraoperative air leak detection rate(37.8% Nebulized ICG combined with near-infrared fluorescence imaging significantly improves intraoperative detection of air leaks, reduces the incidence of postoperative air leaks, and shortens chest tube duration. This technique is convenient, safe, and holds important clinical value for application.

Bronchiolar adenoma (BA) is a rare type of lung tumor characterized by bilayered epithelial cells having a continuous basal layer and a luminal layer. It resembles mucinous adenocarcinoma (MA) on frozen section, with difficulty in distinguishing the basal layer. Immunohistochemistry is the best choice for verifying the diagnosis. This study aimed to comprehensively characterize three cases of BA-combined carcinoma using clinical, histopathological, and genetic features. BA and carcinoma sections were subjected to next-generation sequencing, respectively. It was hypothesized that while different mutation forms matched different regions, BA and lung adenocarcinoma shared the same gene mutation when they co-occurred in the same location. BA with extensive carcinoma is extremely rare and presents diagnostic challenges due to its overlap with conditions such as MA. Because of its distinctive morphological characteristics, BA may be regarded as a low-grade malignancy, particularly during a confusing evaluation. A multifaceted examination of clinical, radiological, immunohistochemical, and genetic data is necessary for an accurate diagnosis.
